Donald Trump's chief of staff said Friday the president was experiencing "mild symptoms" of COVID-19, after the bombshell news of his infection upended the White House race a month before the Republican faces challenger Joe Biden at the polls.
The 74-year-old Trump – who has continued to cast doubt on the seriousness of the pandemic, even as the United States (US) death toll topped 200,000 – announced in an overnight tweet that he and First Lady Melania Trump, 50, had tested positive and were going into quarantine.
Briefing reporters at the White House Friday morning, Trump's chief of staff Mark Meadows said the president was experiencing "mild symptoms" but remained in "good spirits" and "very energetic."
"The American people can rest assured that we have a president that is not only on the job, will remain on the job, and I'm optimistic that he'll have a very quick and speedy recovery."
Meadows said Trump's doctor would continue to attend to him at the White House, declining to give details of any treatment being provided.
Melania Trump for her part tweeted that she was "overall feeling good" and hoping to recover fast.
"Thank you for the love you are sending our way," she wrote.
While its ultimate effect on the race remains unpredictable, the thunderbolt news had immediate electoral consequences for Trump, forcing him to cancel a rally planned later Friday in key swing state Florida.
Further ahead, it looked certain the Republican – who is badly lagging behind Biden in the polls ahead of 3 November – would have to abandon a weekend trip to Wisconsin, another battleground, as well as a tour of western states next week.
And a question mark hangs over his second televised debate, set for 15 October, against Biden, who has made criticism of Trump's coronavirus response his key issue.
Biden, 77, announced Friday that he and his wife Jill had tested negative for coronavirus, saying that they will "continue to pray for the health and safety of the president and his family."
During their first debate on Tuesday in Cleveland – where they stood in close proximity for 90 minutes – Trump mocked the Democrat for his rigorous adherence to mask wearing.
In his statement Friday, Biden said "I hope this serves as a reminder: wear a mask, keep social distance, and wash your hands."
With Trump isolating at the White House, his Democratic rival left after receiving the COVID all-clear on a campaign trip to swing state Michigan.
Contact Tracing
News of Trump's infection came right after one of his closest advisors, Hope Hicks, tested positive –sparking fears of a cluster of cases emanating from the heart of the White House.
Trump met with dozens of people through the week and reportedly went to a fundraiser in New Jersey after it was known Hicks had contracted the virus.
The White House said it was carrying out contact tracing, while Melania Trump's spokeswoman said the couple's 14-year-old son Barron had tested negative.
Vice President Mike Pence, Treasury Secretary Steven Mnuchin and Secretary of State Mike Pompeo all let it be known they had tested negative, and the White House said Supreme Court nominee Amy Coney Barrett was a negative too.
But Republican Party chairwoman Ronna McDaniel, who was last with Trump on 25 September, tested positive earlier this week, according to US media reports.
Contracting COVID-19 is more than a PR disaster for a president who has staked everything on trying to persuade Americans that fears of the virus are overblown.
In what has become an overtly political gesture, Trump almost never wears a mask in public – an example followed by his supporters and many of his aides.
The president has been using large rallies to try to change the subject from his much criticised COVID-19 response, vowing in a speech just Thursday that "the end of the pandemic is in sight."
All that is now on hold, with the clock ticking on the election.
Now Trump has become the world's highest profile patient, proving that all the resources of the White House could not prevent the risk.
As the shock news sent global stocks sliding, leaders including Germany's Angela Merkel and Britain's Boris Johnson wished the president and first lady a speedy recovery – while Russian President Vladimir Putin predicted Trump's "vitality, good spirits and optimism" would see him through.
Technically obese and in his 70s, Trump is in a higher-risk category.
Doctor Daniel Griffin, an infectious disease specialist in the New York area, said Trump had an estimated 20 percent chance of developing severe disease requiring oxygenation, in light of his age and weight. - AFP
